Sediment features, macrozoobenthic assemblages and trophic relationships (δ13C and δ15N analysis) following a dystrophic event with anoxia and sulphi…
2007
Macrozoobenthic assemblages and stable carbon (delta C-13) and nitrogen (delta N-15) isotope values of various primary producers (macroalgae and angiosperms) and consumers (macroinvertebrate filter/suspension feeders, deposit feeders, detritivores/omnivores and carnivores and fishes) were studied in the Santa Giusta lagoon (Sardinia, Italy) before (spring) and after (autumn) a dystrophic event which occurred in the summer of 2004. A few days after the dystrophy, the physico-chemical characteristics of sediments and macrozoobenthic assemblages were also investigated. In the latter occasion, high total organic carbon (3.9%) and organic matter (15.9%) contents of surface sediments went togethe…
Generalist invasion in a complex lake food web
2023
Invasive species constitute a threat not only to native populations but also to the structure and functioning of entire food webs. Despite being considered as a global problem, only a small number of studies have quantitatively predicted the food web-level consequences of invasions. Here, we use an allometric trophic network model parameterized using empirical data on species body masses and feeding interactions to predict the effects of a possible invasion of Amur sleeper (Perccottus glenii), on a well-studied lake ecosystem. We show that the modeled establishment of Amur sleeper decreased the biomasses o ftop predator fishes by about 10%–19%. These reductions were largely explained by inc…
La diffusion des NTIC au sein du réseau urbain français et le rôle des acteurs publics
2001
The study deals with the ways in which the general public and the government make use of new information and communication technologies. We analyze the physical locations of Internet sites with “fr” as their domain names. The data were provided by the French NIC center (AFNIC). Using this sample (a quarter of all French sites), we find a rather even distribution of French sites in the Paris area plus the other main French cities, and the remainder of France. In addition, we try to enumerate the initiatives of the public actors responsible for the regional planning of the new information and communication technologies. Firstly, we clarify the economic and legal framework in which public acto…
Ważność kryteriów oceny wiarygodności witryn internetowych na podstawie badań
2019
Wiarygodność witryny internetowej oznacza przeświadczenie użytkownika, że jego oczekiwania dotyczące otrzymania określonych informacji z tej witryny zostaną spełnione bez ponoszenia dodatkowych, nieuzasadnionych kosztów: ekonomicznych, społecznych, psychologicznych, prawnych, etycznych. Dokonywanie oceny wiarygodności witryn wymaga jej konceptualizacji i operacjonalizacji. W literaturze przedmiotu zidentyfikowano różne wymiary wiarygodności witryn oraz wiele zestawów kryteriów jej oceny. Jednak w zasadzie brak jest określenia ważności poszczególnych kryteriów, co pozwoliłoby na tworzenie rankingów witryn. Dlatego celem wstępnych badań przeprowadzonych metodą sondażową było wypełnienie tej l…
Il processo decisionale online: rassegna di studi empirici e confronto tra Siti Internet per l'Aiuto alle Decisioni negli Stati Uniti e in Europa
2005
With the advent of the Internet, decision making researchers have extended their research scope from traditional "offline" contexts to the increasingly more common "online" decision environment. At the same time, on the Web an increasing number of "decision-facilitating websites" have appeared - spaces finalized to help users make "online" decisions. In the present work we a) present and discuss the most important decision facilitating websites; b) review the main results obtained by the fledgling field of Web-based decision research.
Allochthony, fatty acid and mercury trends in muscle of Eurasian perch (Perca fluviatilis) along boreal environmental gradients
2022
Environmental change, including joint effects of increasing dissolved organic carbon (DOC) and total phosphorus (TP) in boreal northern lakes could potentially affects food web energy sources and the biochemical composition of organisms. These environmental stressors are enhanced by anthropogenic land-use and can decrease the quality of polyunsaturated fatty acids (PUFAs) in seston and zooplankton, and therefore, possibly cascading up to fish. In contrast, the content of mercury in fish increases with lake browning potentially amplified by intensive forestry practises. However, there is little evidence on how these environmental stressors simultaneously impact beneficial omega-3 fatty acid …
EL LÉXICO DEL TURISMO EN EL ESPAÑOL DE ARGENTINA: ESTUDIO DE LAS PRINCIPALES PÁGINAS WEB HOTELERAS
2015
El mundo del turismo ha evolucionado en los últimos tiempos de una manera notable gracias al auge de internet. Asimismo, con esta nueva herramienta, este sector ha ampliado su campo de visión comercial y, por lo tanto, ha encontrado una vía más rápida y eficaz para llegar al público. El ámbito de investigación lingüística que se dedica al turismo no ha tardado en hacerse eco de esta nueva situación y, de esta manera, ha empezado a contemplar en su campo de estudio la variante que supone internet en el turismo. Uno de los motivos de este interés es el aumento terminológico que se ha detectado en el ámbito turístico mediante esta vía. Este incremento se debe a la aparición masiva de anuncios …
Relaxation of wet paper by simulations and laboratory-scale experiments
2009
Numerical studies of fiber networks and experiments on wet paper show that tensile force relaxes linearly as a function of logarithmic time. Relaxation rate is faster for wet than dry paper. Simulated permanent deformation after relaxation is clearly higher than that measured in wet paper.
Enabling the full participation of university students with disabilities: seeking best practices for a barrier-free language centre
2015
Recent research has shown that 3.4% of university students in Finland have a diagnosed or observed illness or disability that affects their learning at the university level. The University of Jyväskylä Language Centre embarked on an organised, ongoing research and intervention project to enable appropriate teaching practices to suit the needs of all students. The process, thus far, has shown there is a need to clarify the rights and obligations of students and teachers to enable an atmosphere of mutual trust. A survey of the Language Centre teachers showed that all had taught students with disabilities during their university careers. Teachers wanted more information about disabilities, suc…
